Problems on ruby 1.8.4 (2005-12-24) [powerpc-darwin8.6.0]

[Arthur Vanderbilt]

I'm fixing little problems that my configuration is having with hobix svn
trunk. I'll post them here as I go?

Here is the first one ...

hobix blogs was throwing an exception when there were no blogs that looks
like this:

/usr/local/lib/ruby/site_ruby/1.8/hobix/commandline.rb:133:in
`blogs_weblog': undefined method `-@' for nil:NilClass (NoMethodError)
        from /usr/local/bin/hobix:79

Because although it would respond to sort, there was nothing in the array.
So the following prints the no blogs message as expected.

         else
             puts "** You have no blogs set up.  Use `hobix setup_blogs' to
get started."
         end
